Helping Clinicians Diagnose ECGs With Confidence.
“PMcardio’s STEMI AI ECG Model leverages decades of our ECG morphology research to accurately distinguish acute occlusions from patterns which mimic them, going beyond mere ST-elevation analysis.”
”PMcardio has fundamentally changed how we manage chest pain in the ER. With AI support, my team and I feel more confident making critical ECG decisions within seconds, especially in the out-of-office hours.”
“PMcardio lets me know in seconds whether to head for the closest ED or drive straight to a primary PCI-capable cath lab. Getting a STEMI verdict at first medical contact saves those crucial minutes—and when it’s heart muscle on the line, every minute counts.”
“I feel so passionately that we should embrace the opportunity and adopt innovation like PMcardio that gives near-perfect accuracy for detecting diagnoses such as Atrial Fibrillation in primary care.”
“After implementing PMcardio, we noticed a clear drop in false cath lab activations. The AI accurately flags occlusions while minimizing noise from STEMI mimickers, saving time, resources, and spared patients unnecessary procedures.”

Frequently Asked Questions
What is PMcardio?
PMcardio is a CE-certified AI that reads ECGs and offers a complex assessment of 30+ cardiac abnormalities. Clinically validated in 15+ studies and trusted by over 100,000 clinicians worldwide, it delivers rapid, expert‑level interpretations, empowering emergency physicians, GPs, nurses, paramedics, and cardiologists to act with confidence at the point of care.
Is it safe to upload ECG images to PMcardio?
Yes, your encrypted data never leaves your region. PMcardio is fully GDPR and HIPAA compliant and adheres to the strictest regulatory and security frameworks, including SOC 2 and ISO 27001 certifications.
For a detailed overview of our compliance, data protection practices, and security protocols, visit our Trust Center.
Is PMcardio clinically validated?
Yes, PMcardio has been rigorously validated in more than 15 independent, peer‑reviewed clinical studies. Across these studies, PMcardio AI ECG interpretation outperformed standard‑of‑care methods, delivering:
- 2x sensitivity for early STEMI detection (often on the very first ECG)
- Reduces false STEMI alarms by over 60%, preventing false positive cath lab activations
- Identifies atrial fibrillation (and other arrhythmias) with 98.3 % accuracy – on par with board‑certified cardiologists
For more information, the latest published evidence, and ongoing RCTs, please visit our Research page.
Which ECG formats does PMcardio accept?
PMcardio supports every commercially available 12-lead ECG, whether as a single-page image or a multi-page report.
The only hard requirement is that the ECG (including all its leads) must be printed on electrocardiogram graph paper, where every five small (1 mm) squares, you can find a heavier line forming a larger 5 mm square — this is essentially the standard ECG paper. The entire ECG should appear on one continuous grid, meaning it should not be split across multiple intersecting grids. Additionally, the image must contain only the relevant leads, without any leads from other ECGs intruding into the picture.
Fewer-lead ECGs, such as 1-lead, 3-lead, or 6-lead recordings, are currently not supported.
What ECG abnormalities can PMcardio detect?
PMcardio’s AI-powered ECG algorithms recognise 49 distinct patterns across four major categories:
- Rhythms & arrhythmias: Atrial fibrillation/flutter, supraventricular or ventricular tachycardia, sinus bradycardia/tachycardia
- Conduction disorders: Left/right bundle-branch block, second- and third-degree AV block
- Ischaemia & infarction: Acute ST-elevation myocardial infarction (STEMI) and STEMI equivalents
- ECG measurements: QTc, PR, QRS and nine additional measurements

Is PMcardio just another AI chatbot like ChatGPT or Perplexity?
No. PMcardio is a deterministic, CE-certified Class IIb medical device purpose-built for ECG interpretation, not a conversational large language model (LLM).
- Zero hallucinations: The same ECG file always returns the same diagnosis.
- Evidence-based training: Fixed model weights are derived from 4 million+ clinically labelled ECGs with matched patient outcomes.
- Independent proof: Performance has been independently validated in 15 peer-reviewed validation studies across Europe and the U.S.
- Regulatory oversight: Post-market surveillance and quality-management systems ensure ongoing compliance with Medical Device Regulation.
Learn more about how PMcardio compares to AI chatbots like ChatGPT.
Is PMcardio more accurate than automated ECG machine reads?
Yes. In six peer-reviewed studies, PMcardio has demonstrated up to 2x higher accuracy than conventional ECG algorithms used in standard ECG machines (e.g., GE Marquette 12SL, Philips, Glasgow Algorithm).

Is PMcardio free?
Yes. Start with a Free Plan that lets you analyse up to 5 ECGs per month at no cost. When you need more reports and advanced Pro features, you can upgrade to a paid subscription with:
- Larger monthly ECG quota: run as many studies as your workflow demands.
- AI explainability for STEMI: colour-coded highlights show the waveform segments driving each positive diagnosis.
- 12 validated interval measurements: instant PR, QRS, QTc intervals and more.
